Authorities are on the lookout for a man they say forced his way into a 1100 block Archer Court residence and assaulted a 16-year-old girl Monday night.

The teenager was investigating a loud noise at the front door about 8 p.m. when she came face-to-face with the suspect. Police say he shoved her to the ground, but fled after the victim’s cellular phone began ringing.

She was not seriously injured.

Authorities describe the suspect as a black-haired and goateed Hispanic man in his early 20s, about 6-foot-1 or 6-foot-2 and weighing from 190 to 200 pounds.

Police urge anyone with information about the incident to contact the department at 703-746-6711. Witnesses and tipsters can remain anonymous.
